Because solaris's IDE drivers are somewhat hacky. If you do the comparison
on an IDE sytem, you will most likely end up comparing how sucky solaris's
IDE drivers are to linux, as opposed to comparing the two kernels in
general.
Unless you want to do the legwork of tracking down a system that is
specifically intel ATA-33 only. That may be semi-comparable.
MAYBE ATA-66 is reasonable as well, with solaris 9 x86. Not sure.

errr.. that sounds rather odd. Surely, using gcc x.y.z on sparc linux,
should result in pretty much the same optimization as on sparc solaris,
when it comes to user-level code.
Are you suggesting that there is a known problem with gcc+sparc linux,
or that it is a known kernel problem with sparc linux?
Or just that the solaris sparc kernel interfaces are better optimized for
64bit operations than sparc linux?
